i To a/ZZ whom it may concern:

Be it known that I, JOSEPH C. BECKLEY, a citizen ofthe United States,residing at Dayton,.in the county of Montgomery and State of Ohio, haveinvented certain new and useful Improvements in Upright Water-TubeBoilers; and I do declare theV following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to whichit appertains to make and use the same, reference being hadto the accompanying drawings, and to the Yligures of reference markedthereon, which form a part of this specification.,

This invention relates to improvements in upright water-tube boilers.

The objects of the invention are to make an internal-tiring boiler withcertain well-defined advantages, hereinafter described. By the terminternal firing I mean a boiler in which the 'fire-box is in closedthroughout its sides and top by a water-chamber, so that the gases orproducts of combustion pass from the upper end of the rebox. out througha Yfire-tube, coming in contact with said water-tubes on all sides, andthence extending upwardly around the sides of a steamdrum to superheatthe steam therein. A portion oi the circulating-tubes are deiiectedinwardly from a perpendicular line to baffle or delect the heat risingfrom the fire-box. The heat ,heretofore lost in this type of boil ers bybeing permitted to escape directly Jfrom the fire-box to the outlet-flueis thus utilized in the present case to add further heat to thewater-tubes after it leaves the fire-box and iinally to superheat `thesteam in the drum and make it dry. The result is that a more rapid andthorough generation oi heat is obtained and a greater amount ofthe heatfrom the iire-box is utilized. The casing is detachable from thewater-leg to gain access to the water-tubes or steam-drum, and thenecessity of bricking up the water-tubes, as is commonly the case 1nwater-tube boilers, is avoided, and a Jfurther advantage due to thepresent improvements is that the boiler may be either ortable lorstationary.

Precedmg a detail description of the invention reference is made to theaccompanying drawings, of which- Figure 1 is a vertical elevation of myim* proved water-tube boiler with a portion of the casing broken awayand a portion of the Water-tubes and the steam-drum and other partsappearing in section. Fig. 2 is an enlarged diagram showing thearrangement of the tubes on the line :n :c of Fig. 1. a

In a detail description of the invention similar reference charactersindicate corresponding parts. y

1 designates the re-box, surrounded by a water-leg 2, which increases inarea in its upper terminal and projects a substantial distance above thefire-box, as at 3, thereby reducing the heat-passage from the ire-box-Mounted upon the water-leg is a casing composed oi' sections 4-, 5, 6,and 7 and terminating at its upper end in a cone 8, forming theoutlet-flue. These sections are united at their adjacent ends in amannerto permit of their detachment in order to gain access to the interior ofthe casing. The lower section 4 of said casing flares outwardly from theupper end of the water-leg to increase the area of space throughout thelength of the casing. It will be observed that the volh urne ofwaterwithin the space inclosing the sides of the fire-box is considerablyreduced in thickness as compared with the width of the water-leg abovethe sides of' the fire-box. Therefore it will be seen that the waterwithin this reduced portion of the water-leg will be of covers 9, and anupperseries of hand-holes, I

also closed by means oi' covers 9. A greater' percentage of such matteris prevented from entering the water-tubes from the` water-leg, and thecommon annoyance due to the formation of incrustation onthe interior ofthe water-tubes is prevented.`

Connected with and extending upwardly from the water-leg is a series ofwater-tubes 12, which are connected at their upper ends to a steam -drum13, arranged at the to of the casing and having its top or heat 14braced with a suitable number of stays 15. The head of this steam-drumis provided with. a manhole and cover 16 to permit access thereto. Thewater tubes 12 so interposed between the water-leg and the steamdrum arearranged in inner and outer rows. The tubes of the outer rows and someof those of the innermost row extend in a per- IOC pendicular manner,while some of the tubes of the innermost row slant inwardly. toward thecenter of the steam-drum and connect with said steam-drum at pointsinwardly from the points of lconnections between said slanting tubes andthe water-leg. By thus inclining a desirable number of said tubeseffective means is provided for baffling the heat and causing said heatto disperse in a manner to effectually spread over the surface of thetubes. Suspended from the bottom of the steam-drum 13 in a centralposition is a deflecting plate or shield 17, which lies a suitabledistance above the entrance from the hre-box. This deiiecting-plate 17is suspendedby means of a rod 18, and the purpose of such plate is toprevent the heat or iire from traveling up the center of the assembledtubes. The heat or flames striking this plate as they emerge from thefire-box will be deflected laterally onto the tubes and will practicallyassume a course as indicated by the arrows, Fig. 1. The fire and gasesthus passing throughout the assembled tubes are affled in their passageto the steam-drum 13 by the inclined tubes and striking the bottom ofthe steam-drum are deflected outwardly between the sides of saidsteam-drum and the surrounding casing, from whence it escapes throughthe outlet-flue after a maximum amount of the heat has been utilized. Asbefore stated, the casing constructed of the united sections isdetachable without disturbing the arrangement of the water-leg, tubes,or steam-drum, and the necessity of bricking up the water-tubes, as iscommonly done in upright-boiler tubes, is avoided.

Means are provided for thoroughly and quickly cleansing the water-tubesof the accumulation of soot. These means consist of a circular pipe 11,arranged immediately above the water-leg and surrounding the base of thewater-tubes. This circular pipe 11 has a multiplicity of small holes 19throughout its circular form and in positions to emit small jets ofsteam onto the base of the water-tubes and to thus remove the soot. Thepipe 11 is connected to the steamdrum 13 by an upright pipe 20, which iscontrolled by a valve 21 and by means of which the steam is admitted tothe pipe 11 for the purposes specified.

Having described my invention, I claim- 1. In an upright water-tubeboiler, a firebox, a water-leg surrounding said fire-box and projectinginwardly above the sides of said fire-box, a cylindrical casing insections mounted upon said water-leg, a steam-drum j in the upperportion of said casing, a series of perpendicular water-tubes connectingthe water-leg and the stream-drum, and a series of inclined water-tubesconnecting the water-leg and steam-drum at points inwardly from thepoints of connection of the perpendicular tubes with said steam-drum.
